15. Collinear dynamics beyond DGLAP

The DGLAP evolution equations are arguably the most important evolution equations for collider physics applications. However, DGLAP doesn’t capture correlations in fragmentation, which e.g. enter in dihadron fragmentation or the study of energy flow within jets. In this talk I present a general non-linear collinear evolution equation, that accounts for these correlations. These evolution...

16. Jet veto resummation for $pp \to H$+jet with NNLL$'$+NNLO uncertainties

Pedro Cal (DESY)

Many Higgs analyses divide the data into exclusive jet bins since the background decomposition changes considerably depending on the number of jets in the final state. In this talk we present our work on exclusive Higgs+jet production via gluon fusion, with a veto on additional jets. We perform the resummation of jet-veto logarithms to NNLL′ accuracy, using a different factorization theorem...

20. Pure quark and gluon observables

Xiaojun Yao (University of Washington)

One application of jet substructure techniques is to disentangle quark- and gluon-initiated jets. Previous studies mainly relied on the difference in the quark and gluon quadratic Casimirs that appear in Sudakov factors. In this talk, I construct a set of pure quark and gluon observables with the collinear drop grooming techniques, utilizing factorization formulas constructed using...
